Where can I go to let people know that I am streaming at the moment?

I have a community of my own, but I have my own social media too, and I'm trying to see how I could leverage my Discord, Twitter, TikTok, and Instagram to kinda let people know that I'm streaming. All I'm thinking about right now is maybe multi-streaming across YT, Twitch, and Tiktok, but what do you guys think?
